  1. 1. Optimization of event selection and fake background estimation in a search for heavy scalars in dilepton final states with the ATLAS detector

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Marius Burman Ingeberg; [2021]
    Keywords : Physics; Particle physics; ATLAS; Standard Model; CERN; LHC; Higgs boson; Exotic Higgs Boson; Dilepton final states; Optimization; Physics and Astronomy;

    Abstract : The discovery of the Higgs boson h in 2012 further confirmed the remarkable accuracy of the Standard Model (SM). Despite this, some compelling excesses in multi-lepton final states were recorded in both major runs of the Large Hadron Collider (LHC). READ MORE

  2. 2. Searching for doubly charged Higgs bosons using same-sign hadronic tau final states - A focused study on the charge-flip background of hadronic taus

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Shi Qiu; [2019]
    Keywords : doubly charged Higgs bosons; neutrino; ATLAS; charge-flip; charge misidentification; Physics and Astronomy;

    Abstract : The search for doubly charged Higgs bosons (H±±) aims at resolving the mass generation mechanism of neutrinos in the Standard Model. The current search by the ATLAS Same-Sign Dilepton group uses the decay product of H±± to a pair of same-sign hadronic τ-leptons, which is an extension of their previous search using same-sign dielectrons and dimuons.

  3. 3. Doubly Charged Higgs Signal with Same-Sign Tau-inclusive Dilepton Final States

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Simon Arnling Bååth; [2018]
    Keywords : ATLAS; same-sign; dilepton; higgs; LHC; signal sample; Physics and Astronomy;

    Abstract : Abstract The current Standard Model of particle physics contains few interactions resulting in a final state with two leptons with the same charge. Any observation of an excess of such same-sign dileptons would be an indication of new physics processes, making it a useful channel when searching for exotic physics. READ MORE
